DETONATING TOY.

SPECIFICATION formingpart of Letters Patent No. 667,642, dated February 5, 1901. Application filed January 14, 1899. Serial No. '702|18I. (No model.)

T a/ZZ who/1t it muy won/morro;

Be it known that LWILLIAM Il. WYTHE, of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Childrens 'lorpedoes or Detonating Toys, of which the following is a specification.

My invention consists of an ordinary playing-marble or other hard body coated with a detonating compound which when thrown against or struck b'y a hard substance will explode only at the point of contact, leaving the surrounding parts unchanged.

My invention is illustrated in the accompanying drawings, in which- Figure l is an elevational View of the nished article, and Fig. 2 a central section showing the dispositionv; of the successive coatings.

Referring to the drawings, A represents a marble or other hard body; B, a coating of essentially non-heat-conlducting size or glue; C, a very thin coating of detonatable material, and D an incombustible envelop or protective covering. It has been necessary to greatly exaggerate the thickness of the several layers or coatings in thedrawings for the purpose of fully illustrating the same, as in actual practice the thickness of said coatings is not much more than that of aline and that olfthe detonatable material being extremely t 11n.

The detonating compound may be applied either in the form of a paste or the marble may be coated with a strong size or other adhesive material and afterward rolled in a dry powder composed of the detonating compound.

The detonating compound consists' of a readily-oxidizable substance, such as sulfur, phosphorus, pyroxylin, suld of antimony, or other sultids, in combination with chlorate of potassium or other chlorates, pcric acid, oxid of silver, nitrate of potassium, or other oxidizing substances in such proportions that the mixture will only detonate at the point of contact when struck. Powdered glass, sand, or`other inert substances maybe added to reduce the explosive force of the mixture in such proportions as may be desired. In practice I prefer a mixture of powdered sulfur and chlorate of potassium in the proportion of forty parts of sulfur to sixty parts of chlorate of potassium. y The sulfur may be mixed alone with the size and applied to the marble as a paste and afterward rolled in dry chlorate of p0- tassiurn in fine powder. I do not, however, limit myself to the above-named ingredients or proportions, as any of many other substances and proportions may be used, pro vided the amount of the oxidizing substance is in excess of the other material.

In order to protect the torpedo from possible danger of tire and to confine the detonation absolutely to the point of contact, I cover it with a thin coating of silicate of soda or other reproof varnish.

I claiml. As an article of manufacture, a repeating torpedo consisting of the combination with a hard ineombnstible body of an uniuterrupted, adherent, locally-detonatable and non-combnstion-maintaining coating for said body.

As an article of manufacture, a repeating torpedo consisting of the combination with ahard incombustible body'of substantially globular form of an uninterrupted, adherent, locally-detonatable and non-combustion-maintaining coating for said body.'

3. As an article of manufacture, a repeating torpedo consisting of the combination with a hard incolnbustible body ot' an unini non-combustion-maintaining coating for said body, said coating comprising an under coat-A Y' ing of an essentially non-heatfcondueting size 01 glue and a thin outer coating ofra mixture of forty parts of powdered sulfur and sixty partis of ohlorate of potassium.

5. As an article of manufacture, a repeating torpedo consisting of a. hard incombustible body, an uninterrupted, adherent, 1o-

cally-detonatable and non-oombustionmain tining coating for said body and an outel adherent inoombustible envelop oreovering.
